Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed July 23, 1909. Serial No. 509,143.

To all whom it may concern:

Be it known that I, AMBROSE S. Vosn, a citizen of the United States,residing in Brookline, county of Norfolk and State of Massachusetts,have invented an Improvement in Machines for Trimming the Edges of Bootsand Shoes, of which the following description, in connection with theaccompanyingdrawings, is a specification, like characters on thedrawings representing like parts.

This invention relates to machines for trimming the edges of boots andshoes, and

' has for its object to provide a simple and efficient attachment, whichis especially de signed and adapted to be applied to edge trimmingmachines employing a rotary cutter having a plurality of stationary orfixed knives or blades. To this end, I employ a sleeve, which isdesigned to be fittedonto the rotatable shaft to which the rotary cutteris fastened, and provide the said sleeve with an annular flange, whichcarries a plu rality of beds, which cooperate with the blades or knivesof the rotary cutter. The sleeve has mounted on it a ring, whichcooperates with the said beds by a pin and cam slot arrangement foradjusting the beds with relation to the cutting edges of the knives orblades, to uncover the same more or less according to the depth of thecut. Provision is made for rendering the sleeve fast on the shaft andfor keeping the beds and their operating ring in close engagement aswill be described. These and other features of this invention will bepointed out in the claims at the end of this specification.

Figure 1 is an elevation of a sufiicient portion of an edge-trimmingmachine embodying this invention to enable the same to be understood.Fig. 2, an enlarged longitudinal section of the shaft and the attachmentthereon. Fig. 3, a detail in elevation to be referred to. Fig. 4:, adetail in plan to be referred to. Figs. 5 and 6, elevations of thesleeve and the beds carried thereby. Figs. 7 and 8, details of a bedremoved from its supporting sleeve. Fig. 9, a detail of the ringemployed to adjust the beds, and Fig. 10, a modification to be referredto.

Referring to the drawings, 64 represents a rotary shaft having bearingsin a framework b, which may be of any suitable or desired construction,said shaft being shown as provided with the pulley c for driving thesame. The shaft a has secured to it a rotary cutter cl having aplurality of knives or blades 6, which have a fixed or nonadjustablerelation to the body of the rotary cutter. In the present instance, theknives or blades are represented as integral with the body portion ofthe rotary cutter, which is not herein claimed, as it forms thesubjectmatter of another application Serial No. 422581 filed March 23,1908, by Albert E. Ayer. The rotary cutter b is shown as mounted on thetapered end of the shaft (1 and is secured thereon by a screw 9 extendedthrough a shield or guard h.

The present invention has for its object to provide a simple andefiicient attachment, which is capable of being readily applied to theshaft a and is provided with a plurality of adjustable beds 10, whichextend between the blades or knives and are adjustable with relation tothe cutting edges thereof.

The attachment referred to comprises a sleeve 12, having an annularflange 13 at its front end, which carries the beds 10. For this purpose,the flange 13 is provided with a plurality of slots 14 for the receptionin each of a narrow neck portion 15 of a bed, which is provided at theends of the neck portion 15 with upright portions or wings 16, 17, whichare designed to engage the opposite surfaces of the annular flange 13and offer a broad bearing for guiding the bed in its movement radiallywith relation to the shaft. The radial movement referred to, is effectedby rotary movement of a ring or collar 18 normally loose on the sleevebehind the annular flange and operatively connected with the bed by apin and cam slot connection. In the present instance, the rear uprightwall 17 of the bed is provided with a slot 19 extended transversely ofthe bed and inclined, and the ring 18 has extended from its front face apin 2-0, which is designed to enter said inclined or cam slot, so that,rotation of the ring causes the pin to travel longitudinally of the slotand effects bodily movement of the bed in the radial slot 14 in itscarrier. Provision is made for limiting the rotary movement in oppositedirections, so as to retain the pin 20 in the slot of the bed with whichit cooperates, which may be accomplislied by providing the ring 18 withstop pins 21, 22, on opposite sides of the actuating pin 20 (see Flg.9), which stop pins are adapted to bring up against the opposite sidesof the wing 17 in which the slot 19 is made, or the ends of the slot 19may be closed as repre sented in Fig. 10. After the beds 10 have beenadjusted with relation to the cutting edges of the blades or knives,they may be secured in their adjusted position by making the ring 18fast on the sleeve 12, which may be accomplished by a set screw 25. 7

Provision is made for securing the sleeve 12 to the shaft a, which iseffected as shown by a screw 26 carried by a ring 27 mounted on thesleeve 12, said screw extending through a hole 28 in the sleeve 12.

Provision is made for keeping the bed actuating ring 18 in close contactwith the beds 10, and for this purpose the sleeve 12 is provided withscrew threads 30, which are engaged by a nut or internally threaded ring31, the hole 28 in the sleeve 12 being made larger than the screw 26 topermit the ring 27 to be moved lengthwise of the sleeve.

The bed carrying flange 13 may have secured to it as by screws 33 a ring34 through which are extended pins or rods 35 attached to a featheredger ring 36, which is normally projected over the knives e by springs37, the outward movement of the feather edger ring by the springs 37being limited by pins or rods 38 fast to the ring 3% and looselyextended through the feather edger, the pins or rods 38 being headed tolimit the outward movement of the feather edger ring 36. The featheredger is not herein claimed broadly, as it forms the subject-matter ofanother application, Serial No. 196238 filed by me on the third day ofJuly 1909.

The construction herein shown is capable of being used on anyedge-trimming machine, but is especially designed and adapted to be usedon the well-known Buzzell trimming machine, and it is only necessary toremove the rotary tool of the Buzzell machine from its shaft and replaceit with the attachment herein shown.

To facilitate adjustment of the beds with relation to the knives orblades, the ring 18 may be provided with a scale or indications 39 asshown in Fig. 4:, with which cooperates a pointer on index 10 attachedto the bed 10 in line with said scale.
